Well, I'm pretty sure this isn't the answer you want, as you are almost certainly looking for a query that will combine overlapping times into contiguous ones.
So, in the interests of getting a better description of your requirements, is this the query you need:
select id, min(timefrom),max(timeto)
from <unnamed_table>
group by id;
